A forced srp switchover was done and sessions migrated to the backup chassis. The primary chassis became standby and the sessmgr crash was seen.

Important condition for this bug to occur would be having diffrent nat-realms to be configured inside firewall policy.
for active and standby chassis. Basically its an invalid config.
